Patent SE-8600055-D0 (SE)
Inventor: TARNAI G
IPC: G01N29/30
Filed: 1986-01-07
Abstract: The control specimen according to the invention consists of a metal basic body and artificial inclusions arranged in it, where the inclusions are suitably sintered, non-metallic configurations arranged according to size and distribution conforming to the purpose of the test. During production of the control specimens at least one layer is formed with metal melt, into which inclusion, inclusions is/are inserted conforming to the shape and arrangement of the required fault location or locations. It is practicable to form at least one further upper layer from the metal melt inclusions. Further inclusions may be arranged in the top layer and in given case further top layers are formed with or without inclusions. The artificial defects can be produced either by forming cavities into the layer after solidification and cooling, and inserting the inclusion(s) into the appropriate cavity or cavities, or spreading them into the layer-forming metal melt before solidification.

Abstract: A method and apparatus are provided for increasing the efficiency of treatment of a paper pulp slurry with chlorine gas, such as in the bleaching or delignification of deciduous wood chemical pulps, coniferous wood chemical pulps, and non-wood fibrous chemical pulps. Chlorine gas is intimately mixed with the pulp in a fluidizing mixer (14), the pulp preferably having a consistency of about 7-12%, and then is passed to a retention vessel (20). The discharge of pulp from the mixer to the retention vessel, and from the retention vessel to other treatment structures, is throttled by valves (30, 31) so as to increase the pressure in both the mixer and the retention vessel to above atmospheric, and preferably in the range of about 15-150 psig (1 to 10 bar above atmospheric pressure). The chlorine gas is added to the mixer through one more discs (53) of porous materials having pore sizes in the range of about 5-175 microns, such as porous ceramic or sintered metal discs. The increased pressure during the chlorine treatment, and the introduction of the chlorine gas in the form of minute bubbles, improve the solubility of the chlorine in the pulp slurry and thereby increase the efficiency of treatment. (Figure 1).

Abstract: A protective layer of BaSO4 or BaSO4 mixed with SiO2 is applied in suspension to the inner surface of the glass discharge tube or envelope of a gas discharge lamp of the metal vapour type. The protective layer prevents contact, e.g., of mercury in the discharge chamber with amalgam-forming substances present in the glass surface of the lamp discharge tube. In addition, the crystals of the protective layer re-reflect shortwave ultraviolet radiation back to the layer of luminescent substance, thereby to generate visible light and increasing the efficiency of the lamp. The protective layer results in a marked decrease in the hitherto accepted reduction in the lamp luminance in relation to lamp burning time.

Abstract: A crankshaft carried crankpin carries an eccentric interposed between the crankpin and the slider of a yoke type engine. The eccentric carries a gear to permit rotatable adjustment to be imparted to the eccentric about the crankpin axis. Positioning of the eccentric includes the use of a gear train. A gear set in the gear train has displaceable gears carried by a carrier responsive to engine control means. The movable gear set serves to accelerate or decelerate the rotational speed of a pair of shaft mounted driven gears to momentarily alter their rotational speed so as to in turn rotate the eccentric mounted gear to reorientate the eccentric to the crankpin. Such relocating of the eccentric serves to alter the piston stroke between high and low compression ranges.

Abstract: The number of zero-crossings in each band of a dual-tone multifrequency (DTMF) signal is counted and compared with that in immediately preceding measurement periods. The magnitude of any difference is established and when it is at least equal to a threshold value, pref. one, the input signal is considered to be a DTMF signal. The energy parameter, representative of the tone energy in a signal, is measured in real time in each band, and three threshold values for the difference from average values determined. The measured difference values are compared with the thresholds to determine if a DTMF signal exists. An interference frequency is accepted when occurring in successive measuring periods.

Its piston rod (9) is extendable downwards and over a pulley (8) in the lower end of the piston rod a chain (6) runs that from an upper fastening point in the mast part (4) runs down around the pulley (8) and up again over another pulley (15) fastened in the upper end of the mast part and then once again downwards to be fastened in the fork carriage (5). The hydraulic cylinders of the fork carriage and the mast parts are coupled in parallel but have such relative cross sections that the cylinder (7) of the fork carriage have smaller pressure requirement than the mast cylinders. In the frame of the truck or in a mast part (2) fastened to the truck frame a sensor (11) is arranged close to the lower end position of the piston rod (8) and for cooperating with this in such a way that when the piston rod (8) approaches its lower end position , that is the lifting carriage is approaching its upper end position in the mast part, the sensor is triggered. The sensor is coupled to the hydraulic means that feed hydraulic oil to the hydraulic cylinder reducing the oil flow so that the speed of the carriage is reduced close to the end of the travel of the carriage in the frame part (4) and at lowering the mast movement speed is reduced in the vicinity of the lower end position of the mast parts. <IMAGE>
